Definitions

  • novel substituted 6,7-dihydro-5H-benzo[7]annulene compounds the processes for their preparation, as well as the therapeutic uses thereof, in particular as anticancer agents via selective antagonism and degradation of estrogen receptors.
  • the Estrogen Receptors belong to the steroid/nuclear receptor superfamily involved in the regulation of eukaryotic gene expression, cellular proliferation and differentiation in target tissues. ERs are in two forms: the estrogen receptor alpha (ER ⁇ ) and the estrogen receptor beta (ER ⁇ ) respectively encoded by the ESR1 and the ESR2 genes. ER ⁇ and ER ⁇ are ligand-activated transcription factors which are activated by the hormone estrogen (the most potent estrogen produced in the body is 17 ⁇ -estradiol). In the absence of hormone, ERs are largely located in the cytosol of the cell.
  • ERs When the hormone estrogen binds to ERs, ERs migrate from the cytosol to the nucleus of the cell, form dimers and then bind to specific genomic sequences called Estrogen Response Elements (ERE).
  • EpE Estrogen Response Elements
  • the DNA/ER complex interacts with co-regulators to modulate the transcription of target genes.
  • ER ⁇ is mainly expressed in reproductive tissues such as uterus, ovary, breast, bone and white adipose tissue.
  • Abnormal ER ⁇ signaling leads to development of a variety of diseases, such as cancers, metabolic and cardiovascular diseases, neurodegenerative diseases, inflammation diseases and osteoporosis.
  • ER ⁇ is expressed in not more than 10% of normal breast epithelium but approximately 50-80% of breast tumors. Such breast tumors with high level of ER ⁇ are classified as ER ⁇ -positive breast tumors. The etiological role of estrogen in breast cancer is well established and modulation of ER ⁇ signaling remains the mainstay of breast cancer treatment for the majority ER ⁇ -positive breast tumors.
  • ER ⁇ -positive patients display de-novo resistance or develop resistance over time to such existing therapies.
  • Several mechanisms have been described to explain resistance to such hormone therapies. For example, hypersensitivity of ER ⁇ to low estrogen level in treatment with aromatase inhibitors, the switch of tamoxifen effects from antagonist to agonist effects in tamoxifen treatments or multiple growth factor receptor signaling pathways. More recently, acquired mutations in ER ⁇ occurring after initiation of hormone therapies may play a role in treatment failure and cancer progression. Certain mutations in ER ⁇ , particularly those identified in the Ligand Binding Domain (LBD), result in the ability to bind to DNA in the absence of ligand and confer hormone independence in cells harboring such mutant receptors.

Description

Provided herein are novel substituted 6,7-dihydro-5H-benzo[7]annulene compounds, the processes for their preparation, as well as the therapeutic uses thereof, in particular as anticancer agents via selective antagonism and degradation of estrogen receptors.
The Estrogen Receptors (ER) belong to the steroid/nuclear receptor superfamily involved in the regulation of eukaryotic gene expression, cellular proliferation and differentiation in target tissues. ERs are in two forms: the estrogen receptor alpha (ERα) and the estrogen receptor beta (ERβ) respectively encoded by the ESR1 and the ESR2 genes. ERα and ERβ are ligand-activated transcription factors which are activated by the hormone estrogen (the most potent estrogen produced in the body is 17β-estradiol). In the absence of hormone, ERs are largely located in the cytosol of the cell. When the hormone estrogen binds to ERs, ERs migrate from the cytosol to the nucleus of the cell, form dimers and then bind to specific genomic sequences called Estrogen Response Elements (ERE). The DNA/ER complex interacts with co-regulators to modulate the transcription of target genes.
ERα is mainly expressed in reproductive tissues such as uterus, ovary, breast, bone and white adipose tissue. Abnormal ERα signaling leads to development of a variety of diseases, such as cancers, metabolic and cardiovascular diseases, neurodegenerative diseases, inflammation diseases and osteoporosis.
ERα is expressed in not more than 10% of normal breast epithelium but approximately 50-80% of breast tumors. Such breast tumors with high level of ERα are classified as ERα-positive breast tumors. The etiological role of estrogen in breast cancer is well established and modulation of ERα signaling remains the mainstay of breast cancer treatment for the majority ERα-positive breast tumors. Currently, several strategies for inhibiting the estrogen axis in breast cancer exist, including: 1-blocking estrogen synthesis by aromatase inhibitors that are used to treat early and advanced ERα-positive breast cancer patients; 2-antagonizing estrogen ligand binding to ERα by tamoxifen which is used to treat ERα-positive breast cancer patients in both pre- and post-menopausal setting; 3-antagonizing and downregulating ERα levels by fulvestrant, which is used to treat breast cancer in patients that have progressed despite endocrine therapies such as tamoxifen or aromatase inhibitors.
Although these endocrine therapies have contributed enormously to reduction in breast cancer development, about more than one-third of ERα-positive patients display de-novo resistance or develop resistance over time to such existing therapies. Several mechanisms have been described to explain resistance to such hormone therapies. For example, hypersensitivity of ERα to low estrogen level in treatment with aromatase inhibitors, the switch of tamoxifen effects from antagonist to agonist effects in tamoxifen treatments or multiple growth factor receptor signaling pathways. More recently, acquired mutations in ERα occurring after initiation of hormone therapies may play a role in treatment failure and cancer progression. Certain mutations in ERα, particularly those identified in the Ligand Binding Domain (LBD), result in the ability to bind to DNA in the absence of ligand and confer hormone independence in cells harboring such mutant receptors.
Most of the endocrine therapy resistance mechanisms identified rely on ERα-dependent activity. One of the new strategies to counterforce such resistance is to shut down the ERα signaling by removing ERα from the tumor cells using Selective Estrogen Receptors degraders (SERDs). Clinical and preclinical data showed that a significant number of the resistance pathways can be circumvented by the use SERDs.
There is still a need to provide SERDs with good degradation efficacy.
G. M. Anstead et al. have described 2,3-diarylindenes and 2,3-diarylindenones as binders of estrogen receptors (Journal of Medicinal Chemistry, 1988, Vol. 31, No. 7, p. 1316-1326).
R. McCague et al. have described analogues of (Z)- and (E)-4-hydroxytamoxifen and have tested their binding affinities to estrogen receptors (Journal of Medicinal Chemistry, 1998, Vol. 31, No. 7, p. 1285-1290).
Provided herein are novel compounds able to selectively antagonize and degrade the estrogen receptors (SERDs compounds), for use in cancer treatment.
Provided herein are compounds of the formula (I):

According to SCHEME 1, in which R1, R2, R3, R4, R5 and R6 are defined as described above, a substituted 5-oxo-6,7,8,9-tetrahydro-5H-benzo[7]annulene intermediate (A) is converted in STEP 1 into the corresponding enol triflate intermediate (B) by treatment for example with triflic anhydride (Tf2O) in solution in dichloromethane (DCM) in the presence of a base, for example pyridine, at room temperature. This intermediate (B) is subjected in STEP 2 to a Suzuki coupling with reagent (1) ((S)-1-(3-fluoropropyl)-3-(4-(4,4,5,5-tetramethyl-1,3,2dioxaborolan2yl)phenoxy)pyrrolidine) using for example [1,1′-bis(diphenylphosphino) ferrocene]dichloropalladium(II) (Pd(dppf)Cl2), complex with DCM, as catalyst, in a mixture of dioxane and water and in the presence of a base, for example cesium carbonate (Cs2CO3), at room temperature or by heating up to reflux. The preparation of reagent (1) is described hereunder in SCHEME 2.
The intermediate (C) obtained is brominated in STEP 3 using for example pyridinium tribromide in DCM or tetrahydrofuran (THF) at room temperature. This bromo derivative intermediate (D) is then subjected in STEP 4 to a second Suzuki coupling with a suitable boronic reagent R6B(OR′)2, wherein —B(OR′)2 is a boronic acid or a pinacolate ester and R6 is as above defined, using for example Pd(dppf)Cl2, complex with DCM, as catalyst, in a mixture of dioxane and water as solvent and in the presence of a base, for example Cs2CO3, at room temperature or by heating up to reflux.
In the above-described reactions, it can be necessary to protect reactive functional groups, for example hydroxy, amino, thio or carboxy groups, where these groups are desired in the final product, to avoid their unwanted participation in the reactions. Conventional protecting groups can be used in accordance with standard practice, for example, see T.W. Greene and P.G.M. Wuts in “Protective Groups in Organic Chemistry”, John Wiley and Sons, 2006.
When R3 or R5 represents a —OH group, this —OH group is protected, for example as a pivaloyl ester. Deprotection can be performed just after STEP 3 or after STEP 4 by treating, with an aqueous solution of sodium hydroxide 2N (NaOH), a solution of the pivaloyl ester in methanol (MeOH) at room temperature, followed by acidification with an aqueous solution of hydrogen chloride 2N (HCl).
When R3 represents a —COOH group, this —COOH group is protected, for example as a methyl ester. Deprotection is performed just after STEP 4 by treating, with an aqueous solution of sodium hydroxide (NaOH) 2N, a solution of the methyl ester in MeOH at room temperature, followed by acidification with an aqueous solution of HCl 2N.
In an embodiment, it can be advantageous to use a variation of SCHEME 1, called SCHEME 1a depicted below, that consists in transforming intermediate (D) into a boronate derivative which is engaged in a Suzuki coupling with an halogenated derivative R6-Hal, wherein R6 is as above defined and Hal represents a halogen atom selected from a chlorine, a bromine or an iodine atom. Deprotection of the —OH group or —COOH group of R3 or R5 can be performed before or after STEP 1 or STEP 2 of SCHEME 1a, as explained above.
Figure US09714221-20170725-C00018
STEP 1 of the above SCHEME 1a consists of reacting intermediate (D) with 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(1,3,2-dioxaborolane) using for example Pd(dppf)Cl2, complex with DCM, as catalyst, in a mixture of dioxane and water and in the presence of a base, for example Cs2CO3, at about 80° C. Intermediate (D′) obtained is engaged in STEP 2 of the above SCHEME 1a in a Suzuki coupling with R6-Hal, wherein R6 and Hal are as above defined, using for example Pd(dppf)Cl2, complex with DCM, as catalyst, in a mixture of dioxane and water as solvent and in the presence of a base, for example Cs2CO3, at about 70° C.
In another embodiment, it can be advantageous, when the compounds of formula (I) are such that R3 is a —COOH group, to use a variation of SCHEME 1, called SCHEME 1b depicted below.
Figure US09714221-20170725-C00019
Hereinabove SCHEME 1b describes the synthesis of the compounds of the formula (Ib) wherein R3 represents a —COOH group, by generating the —COOH group from the —OH group of R3 of the compounds of formula (Ia) wherein R1, R2, R4 and R6 are as above defined in formula (I). In STEP 1 of SCHEME 1b the —OH group of R3 in the compounds of formula (Ia) is transformed into a triflate group with, for example Tf2O in DCM with a base, for example pyridine, at room temperature.
The intermediate (K) obtained is then carbonylated in STEP 2 of SCHEME 1b under 2 to 10 bars of carbon monoxide (CO) at about 70° C. in a mixture of MeOH and N,N-dimethylformamide (DMF) using for example palladium acetate (Pd(OAc)2) and 1,3-bis(diphenylphosphino)propane (P(Ph)2-(CH2)3—P(Ph)2) as catalytic system.
The methyl ester of formula (Ib) then obtained is deprotected as defined above, so as to obtain compounds of formula (I) wherein R1, R2, R4 and R6 are as above defined in formula (I) and R3 is a —COOH group.
In another embodiment, it can be advantageous as well, when R3 represents a —COOH group, to use a variation of SCHEME 1, called SCHEME 1c depicted below. This SCHEME 1c is an alternative process to the above SCHEME 1b.
Figure US09714221-20170725-C00020
Hereinabove SCHEME 1c describes the synthesis of the intermediates (C′″) as defined above by generating the —COOMe group from the —OH group of intermediates (C′) wherein R1, R2 and R4 are as above defined in formula (I). In STEP 1 of SCHEME 1c, the —OH group is transformed into a triflate group with, for example, Tf2O in DCM with a base, for example pyridine, at room temperature.
The intermediate (C″) then obtained is carbonylated in STEP 2 of SCHEME 1c under 2 to 10 bars of CO at about 70° C. in a mixture of MeOH and DMF using for example Pd(dppf)Cl2 or Pd(OAc)2 and P(Ph)2-(CH2)3—P(Ph)2 as catalytic system.

The intermediate (E) then obtained is brominated in STEP 2 of SCHEME 1d using for example pyridinium tribromide in DCM or THF at room temperature.
This bromo derivative intermediate (F) obtained is then subjected in STEP 3 of SCHEME 1d to a second Suzuki coupling with a suitable boronic reagent R6B(OR′)2, wherein the —B(OR′)2 group is a boronic acid or a pinacolate ester, and R6 is as above defined, using for example Pd(dppf)Cl2, complex with DCM, as catalyst, in a mixture of dioxane and water and in the presence of a base, for example Cs2CO3, at room temperature or by heating up to reflux.
This intermediate (G) obtained is N-deprotected in STEP 4 of SCHEME 1d using for example a 4N solution of HCl in dioxane, at room temperature.
The NH-pyrrolidine intermediate (H) obtained is amidified in STEP 5 of SCHEME 1d using for example 3-fluoropropionic acid in DMF at room temperature using for example 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCl) as coupling agent.
Finally, the carbonyl of the amide intermediate (J) then obtained is reduced in STEP 6 of SCHEME 1d into the deuteriated amine of formula (Ic) by for example lithium aluminum deuteride (LiAlD4) in ether (Et2O) at room temperature.
When R3 or R5 is a —OH group, this —OH group is protected, for example as a pivaloyl ester. Deprotection is done at the final STEP 6 for example by reduction with LiAlD4.

According to the above SCHEME 2, commercially available compound (a) (4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol) is condensed in STEP 1 of SCHEME 2 in THF at room temperature on (R)-1-N-Boc-3-hydroxypyrrolidine using N,N,N′,N′-tetramethylazodicarboxamide as coupling agent.
Compound (c) thus obtained is N-deprotected in STEP 2 of SCHEME 2 in MeOH at room temperature using an acidic agent for example a solution of HCl 4N in dioxane.
Alkylation of the pyrrolidine nitrogen is then performed in STEP 3 of SCHEME 2 by reacting compound (d) with the corresponding 1,1-disubstituted 1-halogeno-3-fluoro propane, for example 1-iodo-3-fluoropropane in acetonitrile in presence of potassium carbonate (K2CO3) at about 40° C.

The intermediate (A9) then obtained is finally carbonylated in STEP 3 of SCHEME 3 in the presence of a base, for example triethylamine (Et3N) and a catalyst, for example Pd(OAc)2, under 2 to 10 bars of CO in a mixture of DMF and MeOH at about 70° C. to produce intermediate (A10) (1-fluoro 5-oxo-6,7,8,9-tetrahydro-5H-benzo[7]annulene 2-carboxylic acid, methyl ester).

Some compounds of formula (I) were subjected to pharmacological tests for determining their antagonist and degradation effects on estrogen receptors.
Test A: Biochemical Antagonist Activity on Wild Type (WT) and Mutants Estrogen Receptors
Test A involves measuring the in vitro antagonist activity of a compound of formula (I) on estrogen receptors.
The measurements of the antagonist activities were made using an estrogen receptor coactivator assay as described hereunder.
Antagonistic potency of compounds was evaluated using LanthaScreen® TR-FRET ERα Coactivator Assay (ThermoFisher) with modifications. It is a competition assay, where binding of a test compound to a complex comprised of (i) His6-ERα298-554 protein representing ERα ligand-binding domain, (ii) Tb-labeled His6 antibody, (iii) a fluorescein-labeled PGC1α coactivator peptide (EAEEPSLLKKLLLAPANTQ), and (iv) estradiol, results in a decrease of the TR-FRET signal due to dissociation of the coactivator peptide. His6-ERα298-554 proteins were expressed as WT or D538G or Y537S mutants in E. coli and purified by affinity chromatography. The assay works in a homogeneous mix-and-read format. In a typical experiment, a 4 μL mixture of 0.5 nM His6-ERα298-554, 0.5 nM Tb-labeled His6 antibody, 250 nM PGC1a peptide, and 3 nM estradiol in 100 mM potassium phosphate, pH 7.4, 0.01% Tween-20, 0.02% NaN3, 5 mM DTT, was added to 40 nL test compound in DMSO and incubated overnight at room temperature. The TR-FRET 520:495 nm emission ratio was calculated and used to determine the IC50 value from a dose response curve fit to the 4-parameter logistic equation.
The antagonist activity with respect to estrogen receptors in this test is given by the concentration which inhibits 50% of the estrogen receptor activity (or IC50) in nM.
The Table 2 below indicates the biochemical results of antagonist activity on WT and mutants estrogen receptors for compounds of formula (I), and demonstrates that the compounds tested have an antagonist activity regarding estrogen receptors.

Test B: Cell Proliferation/Viability Assay on MCF7 (Breast Tumor Cells) WT and Mutants Cell Lines
Test B involves measuring the in vitro proliferation activity of a compound of formula (I) by analyzing the viability of the tumor cells.
The measurements of the viability were made using a breast cancer cell viability assay as described hereunder.
MCF7 cells expressing (and dependent) on mutants estrogen receptor Tyr 537 Ser or Asp 538 Gly were generated by transfection of MCF7 parental cells (ATCC) with expression vectors coding for different mutants of estrogen receptor Tyr 537 Ser or Asp 538 Gly. The cells were first selected by antibiotic (related to vector expression) and then selected for their growth dependence on estrogen receptor based on their ability to grow in vitro in absence of estradiol (parental cell line die in absence of estradiol).
MCF7 cells (ATCC) or MCF7 cells expressing (and dependent) on mutants estrogen receptor Tyr 537 Ser or Asp 538 Gly were seeded in 384 wells microplate at concentration of 1000 cells/30 μL per well in red phenol free MEM medium containing 5% charcoal dextran striped FBS. The following day, 9 points serial 1:5 dilution of each compound were added to the cells in 20 μL at final concentrations ranging from 3-0.000001 μM. After 7 days of compound exposure, 50 μL of CellTiter-Glo (Promega) was added to the cells and relative luminescence arbitrary units (RLUs) were determined in luminescence plate reader (Envision device). CellTiter-Glo was added to 50 μL medium without cells to determine the background signal.
The percent of viability of each sample was determined as follows: (RLU sample−RLU background/RLU untreated−RLU background)*100=% viability.
The viability activity with respect to estrogen receptors in this test is given by the concentration which inhibits 50% of the viability activity (or IC50) in nM.
The Table 3 below indicates the cell proliferation/viability assay results on MCF7 (breast tumor cells) WT and mutants cell lines, for compounds of formula (I), and demonstrates that the compounds tested have a significant antiproliferative activity regarding estrogen receptors.

Test C: Estrogen Receptor Degradation Activity
Test C involves measuring the in vitro degradation activity of a compound of formula (I).
The measurements of the degradation activities were made using a breast cancer cell ERα in cell western assay as described hereunder.
MCF7 cells (ATCC) were seeded in 384 wells microplate (collagen coated) at concentration of 10000 cells/30 μL per well in red phenol free MEM alpha medium (Invitrogen) containing 5% charcoal dextran striped FBS. The following day, 9 points serial 1:5 dilution of each compound were added to the cells in 2.5 μL at final concentrations ranging from 3-0.000018 μM or 0.1 μM for fulvestrant (using as positive control). At 4 hours post compounds addition the cells were fixed by adding 25 μL of formalin (final concentration 5% formalin containing 0.1% triton) for 10 minutes at room temperature and then washed twice with PBS. Then, 50 μL of LI-COR blocking buffer containing 0.1% Triton was added to plate for 30 minutes at room temperature. LI-COR blocking buffer was removed and cells were incubated overnight at cold room with 50 μL anti-ER rabbit monoclonal antibody (Thermo scientific MA1-39540) diluted at 1:1000 in LI-COR blocking buffer containing 0.1% tween-20. Wells which were treated with blocking but no antibody were used as background control. Wells were washed twice with PBS (0.1% tween-20) and incubated at 37° C. for 60 minutes in LI-COR (0.1% tween-20) containing goat anti-rabbit antibody Alexa 488 (1:1000) and Syto-64 a DNA dye (2 μM final concentration). Cells were then washed 3 times in PBS and scanned in ACUMEN explorer (TTP-Labtech). Integrated intensities in the green fluorescence and red fluorescence were measured to determine the levels of ERα and DNA respectively.
The degradation activity with respect to estrogen receptors in this test is given by the concentration which degrades 50% of the estrogen receptor (or IC50) in nM.
The % of ERα levels decrease were determined as follows: % inhibition=100*(1−(sample−fulvestrant: DMSO−fulvestrant)).
The Table 4 below indicates the estrogen receptor degradation activity results for compounds of formula (I), and demonstrates that compounds tested have a significant degradation activity on estrogen receptors.
